iOS推送通知消息

Question

I want to display a push notifications message in an AlertView.

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {

    NSDictionary *dic = [userInfo objectForKey:@"aps"];
    NSString *message = [userInfo objectForKey:@"alert"];


    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@"Sie haben eine eine Nachricht." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];
}

That's what userInfo variable contains:

I have tried this but *message is nil .

NSString *message = [userInfo objectForKey:@"alert"];

How can I get the "alert" value? Any ideas?.

Thanks in advance.

Answer 1

This is probably what you needed:

NSDictionary *dic = [userInfo objectForKey:@"aps"];
NSString *message = [dic objectForKey:@"alert"];

Answer 2

Using modern syntax, this should get you what you want. The 'alert' value is inside the 'aps' dictionary.

NSString *message = userInfo[@"aps"][@"alert"]
